Apart from comments that Stefano pointed out, the patch looks good.
However, this approach doesn't scale very well. In the future, we should be looking into adding Common Clock Framework into U-boot, so that we can better control the clocks like we do in the kernel.
I fully agree.
Not sure if there is anyone interested or willing to work on this topic though.
Anyway, it is good to see this issue because it shows the right way to follow, even if there is not (yet) anybody ready to implement it.
Regards, Stefano
